Lippia plant named ‘ECOLOPIA1’

ABSTRACT

A new and distinct  Lippia  cultivar named ‘ECOLOPIA1’ is disclosed, characterized by tolerance to humidity, cold and disease, tall height and large leaf size. The new variety is a  Lippia , useful for a variety of horticultural purposes.

Latin name of the genus and species: Lippia nodiflora×Lippia canescens.

Variety denomination: ‘ECOLOPIA1’.

BACKGROUND OF THE INVENTION

The new Lippia cultivar is a product of a planned breeding program conducted by the inventor. Masataka, Ohde in Oyama, Japan. The objective of the breeding program was to produce new Lippia varieties for ornamental commercial applications. The cross resulting in this new variety was made during May 2008.

The seed parent is the patented variety referred to as Lippia nodiflora ‘Campanga Verde’, U.S. Plant Pat. No. 20,120. The pollen parent is an unnamed Lippia canescens. The new variety was discovered on Jul. 1, 2009 by the inventor in a group of seedlings resulting from the 2008 crossing, in a research greenhouse in Oyama, Japan.

Asexual reproduction of the new cultivar ‘ECOLOPIA1’ was first performed at a commercial greenhouse in Oyama, Japan by vegetative cuttings on Jun. 4, 2010. More than 3 generations have been reproduced by vegetative cuttings. Subsequently, propagation has also shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘ECOLOPIA1’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ECOLOPIA1’. These characteristics in combination distinguish ‘ECOLOPIA1’ as a new and distinct Lippia cultivar:

-   -   1. Tolerance to cold temperature.     -   2. Tolerance to disease.     -   3. Tolerance to high humidity.     -   4. Above average height.     -   4. Above average leaf size.

PARENT COMPARISON

Plants of the new cultivar ‘ECOLOPIA1’ are similar to pollen parent in most horticultural characteristics. The new variety however differs in the following characteristics:

-   -   1. Longer internode length.     -   2. Leaves are longer.     -   3. Shorter plant height.     -   4. Significantly more cold tolerant.

Plants of the new cultivar ‘ECOLOPIA1’ are similar to the seed parent, in most horticultural characteristics. The new variety however differs in the following characteristics:

-   -   1. Taller plant height.     -   2. More tolerance for cold temperature. Under conditions with an         average day temperature of 4.5 Celsius, the new variety         maintains 70% of green color while ‘Campagna Verde’ maintains         only 30% of green color.     -   3. Stronger tolerance to disease under high heat and high         humidity conditions.     -   4. Larger leaf size.

COMMERCIAL COMPARISON

‘ECOLOPIA1’ can be compared to the unpatented, unnamed commercial Lippia nodiflora. Plants of Lippia nodiflora are similar to plants of ‘ECOLOPIA1’ in most horticultural characteristics. However ‘ECOLOPIA1’ differs from Lippia nodiflora in the following characteristics:

-   -   1. The new variety is observed sterile. The comparator produces         many seeds.     -   2. Greater cold tolerance.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical flowers and foliage of a plant of ‘ECOLOPIA1’ grown outdoors in Oyama, Japan.

FIG. 2 illustrates a wider view of the plant.

FIG. 3 illustrates a typical stem or “runner” of the new variety.

Plants are typically grown as ground over, the plants illustrated are planted directly in the ground. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘ECOLOPIA1’ plants grown both outdoors and in a temperature controlled greenhouse in Oyama, Japan. Temperatures ranged from −7° C. to 25° C. at night to 3° C. to 50° C. during the day. No artificial light, photoperiodic treatments were given to the plants. Plants were grown both outside research field with plowed soil supplemented with fertilizer containing 8% N. 8% P, and 8% K, and in temperature-controlled and uncontrolled greenhouses in a mixture of Kanuma soil, peat and vermiculite supplemented with the same fertilizer. Measurements and numerical values represent averages of typical plant types.
